Inland Wetlands and Watercourses Commission

The Inland Wetlands and Watercourses Commission (IWWC) is charged with ensuring that all construction occurring within a regulated area (wetlands, watercourse, or 100 year floodplain zone) does not cause any detrimental impacts to the water source. In order for any construction to occur in such a zone, an applicant must first get approval for the construction from the IWWC. The IWWC also certifies adequacy of Erosion and Sediment Control Plans where disturbances exceed one half acre.
